Competitive swim brief twin mermaids (Spin-off of "Competitive Swimsuit Crisis 20 Climax Twin Mermaids") Who's the JAV actress in this video? Amateur? Name revealed!

A manga doujinshi originally released on December 31, 2021, titled "Competitive Swimsuit Crisis 20: Climax Twin Mermaids," this spin-off was produced in February 2026, four years later, in response to requests from readers. It depicts Rina and Mika, the Twin Mermaids, being forced to obey despicable men to protect their beloved younger male teammate from scandal. With their weaknesses exploited, the two are subjected to sexual abuse in the pool, including being made to swim in men's "competitive swim briefs," forced into penis pump play, and being gangbanged. This spin-off consists of 9 full-color manga pages (including 2 pages summarizing the previous work), allowing viewers to empathize with Rina and Mika's plight while reliving how they respond to these humiliating demands.
